Camera v lens help
Hello, I'm trying to up my photography game and I've come to a grinding halt.
This might be a total novice mistake but I can't work out what's going wrong.
I have a Sony NEX-F3 which came with two lenses, a prime and a zoom.
After a while experimenting with these I want to try some shooting with a telephoto lens.
So instead of spending a lot of money on a new Zeiss lens straight away, I thought I'd see how I got on with a cheaper model first.
I bought one on eBay, listed as Pentacon Fast 135mm A7s A6000 with an E-mount adapter.
It fits onto my camera, clunking into place nicely.
But although the screen shows what the lens sees, when I press the capture button it gives me an error message 'attach the lens correctly'.
I have changed the camera's settings onto manual focus but still have the same problem.
Could you tell me if I am missing something please. I assumed, perhaps wrongly, that the e-mount adapter would make this lens useable with my camera. Am I wrong - and if so what should I look for if I want to try another second-hand lens?
Or is it as simple as the adapter not being fitted properly (although, as I said, it seems to lock into place without any problems).
Thanks for your help!
